+## 🔧 **Configuration Updates Applied**
+
+### Key Changes
+1. **Field Name Modernization**:
+   - `listenport` → `listen_address`
+   - `storagepath` → `storage_path`
+   - `metricsenabled` → `metrics_enabled`
+   - `deduplicationenabled` → `deduplication_enabled`
+
+2. **Timeout Extensions**:
+   - All timeout values updated from 300s/3600s to 4800s
+   - Reverse proxy configurations updated to match
+
+3. **New Features Documented**:
+   - Dynamic worker scaling (`enable_dynamic_workers`)
+   - Deduplication size limits (`maxsize = "1GB"`)
+   - Selective ClamAV scanning (`scanfileextensions`, `maxscansize`)
+   - Extended resumable uploads (`max_resumable_age`)
+
+4. **Best Practices Added**:

+- ✅ **Dynamic scaling**: Automatic worker adjustment for varying loads
+- ✅ **Monitoring support**: Comprehensive testing and monitoring tools
+
+## 📋 **Next Steps**
+
+1. **Test the organized structure**: Run tests from new `tests/` directory
+2. **Validate documentation**: Use updated configuration examples
+3. **Monitor performance**: Utilize new monitoring scripts
+4. **Scale as needed**: Leverage dynamic worker scaling for production loads
+
+The HMAC File Server 3.2 is now fully documented and tested with a clean, organized project structure! 🚀

+## Testing
+
+The HMAC File Server includes a comprehensive test suite located in the `tests/` directory.
+
+### Quick Testing
+
+```bash
+cd tests
+
+# Test XEP-0363 protocol compatibility
+./test_final_xmpp.sh
+
+# Test deduplication functionality  
+./test_deduplication.sh
+
+# Test upload queue performance
+./test_upload_queue.sh
+```
+
+### Test Categories
+
+**Protocol Testing**: Validate XEP-0363 v1, v2, v3, and token protocols
+**Performance Testing**: Upload queue, concurrent uploads, large file handling
+**Feature Testing**: Deduplication, resumable uploads, chunked transfers
+**Monitoring**: Real-time server status and upload activity
+
+### Test Data
+
+- Small files (1MB) for basic functionality
+- Medium files (50MB) for performance testing  
+- Large files (4GB) for stress testing extended timeouts
+- Chunked data for upload segmentation testing
+
+For detailed testing documentation, see [`tests/README.md`](tests/README.md).

+## Configuration Best Practices
+
+### Performance Optimizations
+
+**Large File Handling**: The server is configured for efficient large file uploads:
+- Extended timeouts (`4800s`) prevent disconnections during GB-sized transfers
+- Dynamic worker scaling (`enable_dynamic_workers = true`) adjusts capacity automatically
+- Chunked uploads (`chunk_size = "10MB"`) improve reliability for large files
+
+**Storage Efficiency**: 
+- Deduplication (`enabled = true`, `maxsize = "1GB"`) uses hard links to save space
+- Selective virus scanning (`scanfileextensions`) skips large media files for performance
+- Automatic cleanup (`cleanup_interval = "24h"`) maintains disk space
+
+**Network Configuration**:
+- Reverse proxy timeouts must match server settings (`proxy_read_timeout 4800`)
+- Upload size limits should accommodate `max_upload_size = "10GB"`
+- Queue settings (`uploadqueuesize = 50`) balance memory usage and throughput
+
+### Security Considerations
+
+- Use strong HMAC secrets (64+ characters)
+- Limit file extensions based on your use case
+- Enable ClamAV for dangerous file types only
+- Monitor logs for authentication failures
+
+### Monitoring
+
+- Prometheus metrics available at `/metrics` endpoint
+- Log rotation configured to prevent disk space issues
+- Worker scaling and queue metrics help identify bottlenecks

 For production deployments, consider the following reverse proxy best practices:
 
-- **Timeouts**: Set reasonable timeouts (e.g., `proxy_read_timeout 300;` in Nginx) to avoid hanging connections.
+- **Timeouts**: Set extended timeouts (e.g., `proxy_read_timeout 4800;` in Nginx) for large file handling.
 - **Buffer Sizes**: Increase buffer sizes for large file uploads/downloads if needed (e.g., `client_max_body_size 2G;` in Nginx).
 - **Headers**: Always set security headers (`X-Content-Type-Options`, `X-Frame-Options`, `X-XSS-Protection`).
 - **Forwarded Headers**: Ensure `X-Forwarded-For` and `X-Forwarded-Proto` are set for correct client IP and protocol logging.
